Chapter 1: Product introduction |
AI Nap
With AI Nap, users can instantly snooze your PC without terminating the tasks. The system will continue operating at minimum power and noise when user is temporarily away. It keeps downloading files or running applications in quietest state while you are sleeping. Simply click keyboard or mouse, you can swiftly wake up the system in a few seconds.
Noise Filter
This feature detects repetitive and stationary noises (non-voice signals) like computer fans, air conditioners, and other background noises then eliminates it in the incoming audio stream while recording.
AI Booster
The ASUS AI Booster allows you to overclock the CPU speed in Windows® environment without the hassle of booting the BIOS.
Precision Tweaker
This feature allows you to fine-tune the CPU/memory voltage and gradually increase the memory, FSB and PCIE frequency at 1MHz increment to achieve maximum system performance.
C.P.R. (CPU Parameter Recall)
The BIOS C.P.R. feature automatically restores the CPU default settings when the system hangs due to overclocking failure. C.P.R. eliminates the need to open the system chassis and clear the RTC data. Simply shut down and reboot the system, and the BIOS automatically restores the CPU parameters to their default settings.
Green ASUS
This motherboard and its packaging comply with the European Union’s Restriction on the use of Hazardous Substances (RoHS). This is in line with the ASUS vision of creating environment-friendly and recyclable products/packaging to safeguard consumers’ health while minimizing the impact on the environment.

1.4Before you proceed
Take note of the following precautions before you install motherboard components or change any motherboard settings.
• Unplug the power cord from the wall socket before touching any component.
•Before handling components, use a grounded wrist strap or touch a safely grounded object or a metal object, such as the power supply case, to avoid damaging them due to static electricity.
•Hold components by the edges to avoid touching the ICs on them.
•Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that came with the component.
•Before you install or remove any component, ensure that the ATX power supply is switched off or the power cord is detached from the power supply. Failure to do so may cause severe damage to the motherboard, peripherals, or components.
Onboard LED
The motherboard comes with a standby power LED that lights up to indicate that the system is ON, in sleep mode, or in soft-off mode. This is a reminder that you must shut down
the system and unplug the power cable before removing or plugging in any motherboard component. The illustration below shows the location of the onboard LED.

Chapter 1: Product introduction |
1.5Motherboard overview
Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits into it.
Ensure that you unplug the power cord before installing or removing the motherboard. Failure to do so can cause you physical injury and damage motherboard components.
1.5.1Placement direction
When installing the motherboard, ensure that you place it into the chassis in the correct orientation. The edge with external ports goes to the rear part of the chassis as indicated in the image below.
1.5.2Screw holes
Place six screws into the holes indicated by circles to secure the motherboard to the chassis.
Do not overtighten the screws! Doing so can damage the motherboard.
Place this side towards the rear of the chassis

Chapter 1: Product introduction |
1.6Central Processing Unit (CPU)
This motherboard comes with a surface mount LGA775 socket designed for the Intel® Core™2 Extreme / Core™2 Quad / Core™2 Duo / Pentium® Dual-Core / Celeron® Dual-Core / Celeron® processors.
• Unplug all power cables before installing the CPU.
•Connect the chassis fan cable to the CHA_FAN connector to ensure system stability.
•Upon purchase of the motherboard, ensure that the PnP cap is on the socket and the
socket contacts are not bent. Contact your retailer immediately if the PnP cap is missing, or if you see any damage to the PnP cap/socket contacts/motherboard components. ASUS will shoulder the cost of repair only if the damage is shipment/transit-related.
•Keep the cap after installing the motherboard. ASUS will process Return Merchandise
Authorization (RMA) requests only if the motherboard comes with the cap on the
LGA775 socket.
•The product warranty does not cover damage to the socket contacts resulting from incorrect CPU installation/removal, or misplacement/loss/incorrect removal of the PnP cap.
The motherboard supports Intel® LGA775 processors with the Intel® Enhanced Intel SpeedStep® Technology (EIST) and Hyper-Threading Technology.
1.6.1Installing the CPU
To install a CPU:
1.Locate the CPU socket on the motherboard.
P5QL
P5QL CPU Socket 775
Before installing the CPU, ensure that the cam box is facing towards you and the load lever is on your left.

2.Press the load lever with your thumb (A), then move it to the left (B) until it is released from the retention tab.
To prevent damage to the socket pins, do not remove the PnP cap unless you are installing a CPU.

3.Lift the load lever in the direction of the arrow to a 135º angle.
4.Lift the load plate with your thumb and forefinger to a 100º angle (4A), then push the PnP cap from the load plate window to remove (4B).

6.Apply some Thermal Interface Material to the exposed area of the CPU that the
heatsink will be in contact with, ensuring that it is spread in an even thin layer.
Some heatsinks come with pre-applied thermal paste. If so, skip this step.
DO NOT eat the Thermal Interface Material. If it gets into your eyes or touches your skin, ensure that you wash it off immediately, and seek professional medical help.
To prevent contaminating the paste, DO NOT spread the paste with your finger directly.
7.Close the load plate (A), then push
the load lever (B) until it snaps into the |

retention tab. |

1.6.2Installing the CPU heatsink and fan
The Intel® LGA775 processor requires a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance.
• When you buy a boxed Intel® processor, the package includes the CPU fan and heatsink assembly. If you buy a CPU separately, ensure that you use only Intel® certified multi directional heatsink and fan.
•Ensure that you have installed the motherboard to the chassis before you install the CPU fan and heatsink assembly.
•If you purchased a separate CPU heatsink and fan assembly, ensure that you have properly applied Thermal Interface Material to the CPU heatsink or CPU before you install the heatsink and fan assembly.
Your Intel® LGA775 heatsink and fan assembly comes in a push-pin design and requires no tool to install.
To install the CPU heatsink and fan: |
A |
|||
1. |
Place the heatsink on top of the installed |
|||
B |
||||
|
CPU, ensuring that the four fasteners match |
|||
|
B |
|||
|
the holes on the motherboard. |
|||
|
|
|||
|
Orient the heatsink and fan assembly |
A |
||
|
such that the CPU fan cable is closest |
|||
|
|
|||
|
to the CPU fan connector. |
|
||
2. |
Push down two fasteners at a time in a |
|
||
|
diagonal sequence to secure the heatsink |
|
||
|
and fan assembly in place. |

The type of CPU heatsink and fan assembly may differ, but the installation steps and functions should remain the same. The illustration above is for reference only.
3.Connect the CPU fan cable to the connector on the motherboard labeled CPU_FAN.
